A post-cardiac arrest patient on mechanical ventilation develops PaO2 of 250 mmHg on FiO2 1.0. What adjustment should be made?
Answer: Titrate FiO2 down to target SpO2 94–98%
Hyperoxia (PaO2 >300 mmHg) is associated with worse outcomes; FiO2 should be titrated to maintain SpO2 between 94–98%.
Which vasopressor is the first-line agent for post-resuscitation shock unresponsive to fluid resuscitation?
Answer: Norepinephrine
Norepinephrine is the preferred first-line vasopressor for post-resuscitation hemodynamic support due to its combined alpha and beta adrenergic effects.
A post-cardiac arrest patient has persistent coma at 72 hours. What is the MOST appropriate immediate action?
Answer: Perform a standardized multimodal neuroprognostication assessment
Persistent coma at 72 hours warrants a structured multimodal assessment combining clinical exam, EEG, SSEPs, and neuroimaging before any prognostic conclusions.
Which metabolic derangement is MOST commonly associated with post-resuscitation myocardial dysfunction?
Answer: Lactic acidosis from low cardiac output
Post-resuscitation myocardial dysfunction reduces cardiac output, leading to inadequate tissue perfusion and lactic acidosis.
What glucose target is recommended during post-resuscitation care to balance hypoglycemia risk and hyperglycemia harm?
Answer: 140–180 mg/dL
Current AHA guidelines recommend targeting blood glucose of 140–180 mg/dL, avoiding both hypoglycemia and extreme hyperglycemia.
Brain CT imaging at 24–48 hours post-cardiac arrest showing diffuse cerebral edema with loss of gray-white differentiation indicates:
Answer: Severe anoxic brain injury with poor prognosis
Loss of gray-white differentiation with diffuse edema on CT represents severe hypoxic-ischemic encephalopathy and strongly predicts poor neurological outcome.
Which intervention has been shown to IMPROVE survival to hospital discharge in post-cardiac arrest patients with cardiogenic shock?
Answer: Coronary angiography and PCI for culprit lesion
Emergent coronary angiography with PCI of the culprit lesion improves survival when an acute coronary syndrome is the likely arrest cause.
